Tamron SP 45mm f/1.8 Di VC USD Lens For Canon EF - AFF013C-700

The 45mm format is the closest approximation to human field of vision and captures high-resolution shots to an unparalleled degree of resolving power. Furthermore, the integration of VC into a 45mm fast standard prime lens for full-frame DSLR cameras is an industry-first*. Compose an image at will, without regard to shooting distance or ambient lighting constraints – to produce crisp, tack sharp images from F/1.8 full open aperture. The unique synthesis of a VC system in a 45mm lens with a best-in-class MOD of 0.29m** redefines standard distance shooting – freeing the photographer to discover another dimension of personal style.

Features:

High Performance at F/1.8 Full Aperture
The open aperture is set to F/1.8 with optimized critical properties at a higher level: superb optical performance coupled with a VC system, a shorter MOD, and a well-balanced form factor. Rigorous simulation processes performed throughout the design phase are materialized in distinguished resolving power and beautifully-tuned background blur, a prominent feature to a fast-aperture, full-frame compliant optic

Closest Focusing Distance in its Class
The SP 45mm (MOD: 0.29m) offers best-in-class close focusing*. A floating system design feature seamlessly optimizes image quality by shifting elements relative to the focus group in close shooting situations

Ultrasonic Silent Drive (USD)
The USD actuator converts ultrasonic waves into rotational motion that delivers autofocus with responsiveness, accuracy, and speed without so much as a whisper. The photographer can easily use manual focus at any point while the AF system is operating without having to fumble for a switch

Molded Glass Aspherical Elements
Two molded glass aspherical elements deliver planarity in field curvature. These elements ensure superb focusing uniformity over the entire field by compensating for spherical and comatic aberrations

LD (Low Dispersion) Glass
To further compensate for chromatic aberrations, the new SP Series lenses use an LD element. This element helps to deliver crisp, clear images without color fringing

eBAND and BBAR Coating
eBAND (Extended Bandwidth and Angular-Dependency) Coating and BBAR (Broad-Band Anti-Reflection) Coating both provide superior anti-reflection properties. These technologies have been adapted to each lens and provide crystal clear images by suppressing element surface reflections that lead to ghosting and flare. eBAND Coating is a nano-structured layer deployed on the critical element surface. In addition to regular anti-reflection coatings, eBAND Coating offers higher transmissivity and a significant improvement in anti-reflection characteristics against angulated incident rays

Circular Aperture
Even when stopped down two steps, the nine-blade diaphragm maintains its circular shape to deliver nicely-tuned background blur

Fluorine Coating
Developed for industrial optics, fluorine coating offers long-lasting oil and water resistance to the lens. Moisture and smudges wipe away, making it easy to keep your lens clean

Moisture-Resistant Construction
Constructed to prevent moisture from entering the internal mechanisms of the lens, the new SP line is sealed to allow photographers to shoot outdoors in adverse conditions
